1.What TAGRISSO is and what it is used for

TAGRISSO contains the active substance osimertinib which belongs to the protein kinase inhibitor class of anticancer medicines. TAGRISSO is used to treat adults with a type of lung cancer called ‘non-small cell lung cancer.’ It is used when:

You test positive for a ‘T790M mutation’ – see ‘How TAGRISSO works.’

Your cancer is advanced and is worsening despite previous treatments, which may have included a medicine which worked to block ‘EGFR’ (epidermal growth factor receptor).

How TAGRISSO works

A test has shown that your cancer is linked to a specific change in the EGFR gene called ‘T790M.’ This is known as a T790M mutation.

Because of this T790M mutation, medicines that block EGFR may no longer work.

TAGRISSO affects T790M and may help to slow or stop your lung cancer growing. It may also help to shrink the tumour.

If you have any questions about how this medicine works or why this medicine has been prescribed for you, ask your doctor.
